Super Stall,
Don't know where you can get your hands on a Pitts at Redhill. That said, if you fancy something with a little less power you could try one of the following
Redair (formerly Redhill Aviation - I think) - C152 Aerobat
Cubair - that said not too sure what they have! (no help whatsoever!)
Cloudbase - C150 Aerobat.
You could always try further afield. Tiger Club at Headcorn for example. Check out the clubs web sites for further info - sorry I don't have their web addresses
Good luck and have fun but personally aero's make me puke!
